> My guess is that since 2147539884 is larger than MAXINT, we are hitting this
> exception. Was there a specific reason, this check was added in 0.10.2?
> E.g. if the first offset is a key = "key 0" and then we have MAXINT + 1 of
> "key 1" following, wouldn't we run into this situation whenever the log
> cleaner runs?
